Definitions

  • the invention relates to fire extinguishing technology, in particular the prevention and extinguishing of fires in closed rooms.
  • halogen-containing compounds also has a number of disadvantages. These agents can have a toxic effect on humans, because when they are extinguished, their thermal decomposition forms products with a high degree of corrosion.
  • Fire extinguishing systems with devices for producing fluorocarbon compounds are already known, for example from GB-PS 2 020 971.
  • the disadvantage of these systems is the harmful effect of the fluorocarbon compounds on the environment.
  • these systems are of fairly large dimensions and weight, so that they cannot be used very effectively to extinguish fires in means of transport, for example in air traffic.
  • a fire extinguishing device with a housing having an outlet opening, a charge for producing the fire-extinguishing substance and an ignition unit is known.
  • the ignition unit When the ignition unit is actuated, the pyrotechnic or solid fuel charge ignites, the gaseous combustion products of which form the fire-extinguishing substance that enters the fire area through the outlet opening and extinguishes the fire.
  • this device has insufficient effectiveness because the extinguishing capacity of the gaseous combustion products, which are inert solvents, is low.
  • PCT / RU 92/00071 discloses a method for producing a fire-extinguishing mixture, in which a mixture of solid particles and inert gases is formed when the charge consisting of a pyrotechnic composition is burned off becomes.
  • the high degree of dispersion of these particles, their chemical properties and the freshly formed surface ensure a considerable fire-extinguishing effect.
  • the invention is based on the object of developing a method and a device for extinguishing room fires, by means of which an environmentally friendly and fire-preventing medium can be formed and introduced into the space to be protected which is not harmful to health.
  • the extinguishing takes place through the inhibiting effect of the condensed aerosol phase on the flames.
  • the aerosol phase is formed when the solid fuel is burned after ignition of a charge consisting of a pyrotechnic composition, the combustion products first being post-burned by means of the oxygen-containing oxidizing agent, for example the air, and then being cooled to the required temperature.
  • the afterburning of the products of incomplete combustion until they are completely oxidized by atmospheric oxygen (2CO + O 2nd ⁇ 2CO 2nd ; 2NH 3rd + 1.5O 2nd ⁇ N 2nd + 3H 2nd O; 2H 2nd + O 2nd ⁇ 2H 2nd O; CHx + O 2nd ⁇ CO 2nd + H 2nd O) and the neutralization of nitrogen oxides (NOx + CO ⁇ N 2nd + CO 2nd ; NOx + NH 3rd ⁇ N 2nd + H 2nd O; NOx + H 2nd ⁇ N 2nd + H 2nd O; NOx + CHx ⁇ N 2nd + H 2nd O + CO 2nd ) preferably takes place in an ejector jet.
  • the afterburning and the subsequent cooling of the combustion products of the aerosol-forming fire-extinguishing compositions can increase the effectiveness of the fire-extinguishing aerosol and operational safety, since the combustion products contain no life-threatening gases.
  • the device for extinguishing room fires consists of a cylindrical housing 1, in which a combustion chamber 14 is formed adjacent to an end face.
  • a charge 5 of a solid fuel is arranged at the front end, which charge can be, for example, an aerosol-forming agent which contains a nitrate of an alkaline earth metal, an organic combustible binder and an aerosol gas generator, whereby it is an alkaline earth nitrate, potassium nitrate with a specific metallic surface of not less than 1500 cm 2 / g, as a combustible binder, phenol formaldehyde resin with an average particle diameter of not more than 100 ⁇ m, and as aerosol gas generator, dicyandiamide with a particle size of not more than 15 ⁇ m.
  • An ignition unit 3 for igniting the charge 5 is also provided in the combustion chamber 14.
  • an outlet nozzle 2 in the manner of a Venturi nozzle is applied centrally, which opens into the combustion chamber 14 and, after the constriction, has a jet pipe section 6.
  • inlet openings 9 are provided for the supply of air to the jet pipe section 6.
  • an intermediate wall 11 is arranged transversely to the longitudinal direction of the housing 1.
  • a central wall opening 15 is provided in the intermediate wall 11, from which a mixing tube 8 extends coaxially to the housing 1 to the other end face 16 of the housing 1 and opens into the open at this.
  • a swirling device 10 is arranged in the annular gap between the beam pipe section 6 and the mixing pipe 8.
  • annular cooling space 7 between the mixing tube 8, the intermediate wall 11, the other end face 16 and the wall of the housing 1 is closed.
  • an inlet connector 12 and an outlet connector 13 are provided, which are connected to the annular cooling space 7.
  • the cooling space is connected to a cooling system via the inlet connection 12 and the outlet connection 13, e.g. from a motor vehicle or a marine engine, connected and filled with a coolant.
  • the ignition device 3 is triggered, whereby the charge 5 is ignited.
  • the resulting combustion products emerge from the combustion chamber 14 due to the explosion pressure through the outlet nozzle 2 and the jet pipe section 6 and are blown into the air in the mixing pipe 8 at the free end of the jet pipe section 6 and mix with it.
  • the combustion products are afterburned by means of the air until they are completely oxidized and then cooled to the required temperature.
  • mixing tube 8 In the fire extinguishing device described only one mixing tube 8 is provided. Depending on the requirements for the outlet temperature of the aerosol and the length of the aerosol jet, however, a plurality of mixing tubes 8 can be provided in parallel, into each of which a jet tube section 6 of an outlet nozzle 2 extends, which is connected to the combustion chamber 14. This divides a large jet into several thinner jets, which results in better cooling and better mixing with the air, and consequently more effective afterburning of the unreacted combustion products.
  • the non-contact Cooling the aerosol eliminates "contamination" of the aerosol by the decomposition products of the coolant and is therefore extremely environmentally friendly.
  • Both ambient air and any other gaseous oxidant can be used as the oxidizing agent.
  • the air can be supplied under pressure to improve the air supply and to extend the aerosol jet. However, operation without increased pressure is also possible.
